Detailed Description

Class for handling depth clipping range. It is used to perform checks in case if global (for the whole view) clipping planes are defined inside of SelectMgr_RectangularFrustum class methods.

Constructor & Destructor Documentation

SelectMgr_ViewClipRange()

SelectMgr_ViewClipRange::SelectMgr_ViewClipRange ( )

inline

Creates an empty clip range.

Member Function Documentation

AddClippingPlanes()

void SelectMgr_ViewClipRange::AddClippingPlanes	(	const Graphic3d_SequenceOfHClipPlane &	thePlanes,
		const gp_Ax1 &	thePickRay
	)

Add clipping planes. Planes and picking ray should be defined in the same coordinate system.

AddClipSubRange()

void SelectMgr_ViewClipRange::AddClipSubRange ( const Bnd_Range &  theRange )

inline

Adds a clipping sub-range (for clipping chains).

ChangeUnclipRange()

Bnd_Range & SelectMgr_ViewClipRange::ChangeUnclipRange ( )

inline

Returns the main unclipped range; [-inf, inf] by default.

DumpJson()

void SelectMgr_ViewClipRange::DumpJson	(	Standard_OStream &	theOStream,
		Standard_Integer	theDepth = -1
	)		const

Dumps the content of me into the stream.

GetNearestDepth()

Standard_Boolean SelectMgr_ViewClipRange::GetNearestDepth ( const Bnd_Range &  theRange, Standard_Real &  theDepth  ) const

inline

Calculates the min not clipped value from the range. Returns FALSE if the whole range is clipped.

IsClipped()

Standard_Boolean SelectMgr_ViewClipRange::IsClipped ( const Standard_Real  theDepth ) const

inline

Check if the given depth is not within clipping range(s), e.g. TRUE means depth is clipped.

SetVoid()

void SelectMgr_ViewClipRange::SetVoid ( )

inline

Clears clipping range.
